Method for defining metropolitan regions based on regional inter-city flow intensity measurement model

Abstract

The invention discloses a method for defining metropolitan regions based on a regional inter-city flow intensity measurement model. The method includes the following steps that 1, the urban agglomeration area range to be measured and inter-city flow associated cities are determined; 2, itemized regional inter-city flow intensity of all groups of associated cities is measured respectively according to the determined associated cities, and five sub items, namely economic flow, passenger flow, cargo flow, technical flow and information flow are included; 3, comprehensive inter-city flow intensity and the membership degree thereof of the central city and other associated cities are calculated through weighing according to the five itemized regional inter-city flow intensity values; 4, the above-mentioned data are recorded into an ArcGIS library, and a regional inter-city flow database is established through correlation between spatial data and table data; 5, data in the established regional inter-city flow database is subjected to four groups of naturally intermittent type clustering analysis, and the metropolitan region range in a narrow sense and a broad sense is finally determined. By means of the method, urban linkage intensity can be measured quantitatively and comprehensively in a multi-factor mode, and accordingly the multi-sphere range of the metropolitan region is defined.

Description

technical field [0001] The invention belongs to the field of regional analysis in urban planning, and in particular relates to a method for quantitative analysis, measurement and calculation of inter-city relations in urban planning regional analysis and large-scale delineation of specific regional ranges. Background technique [0002] With the development of society and economy and the advancement of globalization and informatization, the status and role of cities in regional development have been strengthened day by day, and the social and economic connections between cities within regions have become closer and more complex. The delineation of the scope of all levels of the circle played a greater role in influence. [0003] So far, in the field of urban planning, the delineation of metropolitan areas has mostly used economic geography models, such as: economic distance method, economic gravity method and economic field strength method, simply through the economic data of...

AI Technical Summary

Problems solved by technology

This kind of method has the problems of single perspective and single element, and does not take into account other social factors that affect the degree of inter-city connection except direct economic impact; in addition, the current delineation methods mostly use perceptual and empirical judgments on the impact of central cities on other cities. The interval value of the city's economic influence, and then determine the constituent cities in each circle of the metropolitan circle

In general, there are still many problems in the current traditional method of delineating metropolitan circles, and it is not suitable for large-scale regional urban analysis.
